All-electric heat pumpFully gas-free heating
Completely replace your gas boiler. Heating, hot water and cooling — all electric. Net from €6,925 after ISDE subsidy.
Fully off the gas grid
An all-electric heat pump fully replaces your gas boiler: heating, hot tap water and in many cases also cooling — all electric. The gas connection can be removed entirely, which also saves on the gas standing charge.
This is the most sustainable option. With solar panels your home runs on largely renewable energy. All-electric is best suited to well-insulated homes (label B or better) with low-temperature heating.
All-electric benefits

Insulation
Energy label B or better. Good roof and wall insulation.
Heating system
Underfloor heating or low-temperature radiators preferred.
Outdoor space
Space for outdoor unit on wall, garden or flat roof.
Buffer tank space
Indoor space for the buffer tank (typically 180–300 L).

Frequently asked questions
When is all-electric the right choice?+
For well-insulated homes (label B+) with underfloor heating or LT radiators. New construction is ideal. For older or poorly insulated homes hybrid is usually a better fit.
Can I keep my radiators?+
Often yes, but at a lower flow temperature (35–55°C instead of 70°C+). For older radiators we may recommend upgrading to LT models in critical rooms.
How much electricity does it use?+
A typical home (120 m²) uses 3,000–4,500 kWh per year for heating + hot water. Combined with solar panels often net-zero.
Does it work in winter?+
Yes, down to -15°C (some models -25°C). The buffer tank ensures stable hot water also on cold days.
